"It is pretty brazen to do that, especially in a Walmart parking lot," Port St. Lucie Police Det. Keith Boham said. "There are a lot of cameras there."

Surveillance video showed the getaway car pull up behind the victim's car. It was a newer-model, black Honda with an Illinois license plate. The driver was a man with shoulder-length hair and a goatee.

Police said surveillance video showed the woman using the victim's credit card at a Sunoco gas station in Stuart, just off Interstate 95.
